Ordered. These should correct the issues with the HA-S600s. Will let everyone know how they are.

It wouldn't surprise me if these out do the HA-S500 as well. These look to be the exact same size as the HA-S600. Probably replacing them with these.. If so they are actually smaller circumaural vs on ears. Think momentum size.

Dunu has decided to correct some mistakes made with a few of us who bought the DN-1000. That's all I wanted, for them to show us the respect we have shown them by trying a product from a company we know little about. Kudos for doing the right thing.

JVC cheap stuff you have to take seriously. Like them HA-MR55X. I am thinking of giving them a go as well. The HA-S600 had some potential with their 40mm carbon drivers but had some scooped out mids with a mid bass hump. Not the most refined sound but was actually more capable than most $30 cans..The bass especially was silly for the cost.. Sold on carbon/ carbon naotube tech. The HA-S400 and HA-S500 are much better than the older JVC cans and these HA-S660s being the newest.

Take these cans very seriously. $32 for these..I am gonna predict another big hit here at headfi.

Head-fi buddies here who were thinking about buying the Dunu-1000, I would have to regrettably suggest that you don't buy their products, specifically the DN-1000. You can look the Dunu-1000 thread if you're curious why I'm suggesting this, but in a nutshell, I just feel like their business practices aren't above board. And it's a shame I have to say this to clash with what I stated about the earphone itself in previous posts over the past couple of weeks. Of course, the final decision is yours to make. Just my two cents.

Hopefully at least the dude comes back and says that the warranties will be honoured.

Low dive is good, feeling of control is good, but a little lacking in the extension.

Human voice is clear and smooth, strong sense of line, very suitable for listening to pop music.

High-frequency part sounds transparent, a sense of space and field is good.

HA-S660 resolving power is also good, in the high-frequency side with outstanding performance, the sound is transparent, strong spatial sense, vocal and instrumental sound clear and legible. When worn can isolate well from external noise and is comfortable to wear, no pressure.

Earmuffs are made of a soft leather package.

The accessories are lacking

Don't know what is reviewer's reference here, no comparisons were made.

However, for a carbon diaphragm that wasn't burned in yet, sounds promising.

Incredible, but for those of you who like me found the M200's medium tips too small, but the large tips too big, I've finally found a tip that fits the M200, seal well so that it doesn't push out of my ear, and gives me a great balanced sound. This tip is actually the Comply TX500. Perfect fit, seals great, and balances the bass, mids and treble (actually pushes the vocals more forward). Sub-bass is is concentrated on more than any mid-bass. I generally don't like Comply tips on my phones, but these seem just right for M200. Violins are even richer and more refined. Great find after deciding to tip roll for the M200.

Ericp, will the DN-1000.silicone stock tips fit the M200? Also, which of the two has faster bass response and also bassier?

Been away for awhile but I noticed there's no new discoveries worthy of the thread yet. I'm pretty hyped about them new Fostex phones but will have to see how the really fare. Initial impressions seem to be very promising.
